Abstract

One of the most promising methods proposed to mitigate global CO2 and one that is useful in enhanced oil recovery is carbon sequestration, a process in which CO2 is pressurized and injected into geologic formations. A technical challenge surrounding the geologic sequestration of CO2 is tracking the movement of the fluids pumped underground. Monitoring, verification, and accounting activities related to CO2 storage are important for assuring that any sequestered CO2 does not escape to the surface and can be considerably aided by reflection seismic-based detection methods. Through the use of lab-scale velocity measurements under in-situ conditions, combined with multiple 3D reflection seismic surveys, we hope to effectively track the movements of CO2 after injection.
